How is everyone? I’ve decided to build my own Wii sensor bar to use with the Dolphin emulator. I am facing a problem with the infrared led output. As you can see from the picture below, the official Wii bar is much brighter than the one I’ve built. The LED specs are as follows: DC 1.5-5V 80mA 0.1W IR 940nm
My circuit has 124 ohms of resistance in two locations creating a voltage divide. The LEDs are supplied with 4.5V and the current at approximately 70 mA. The LEDs are ran in parallel.
Is there something wrong with my circuit or is there a more powerful infrared emitter I could use?
